Phones, computers and AI hardware depend on non-volatile memory (NVM), which keeps data without power. Future data demands may need storage a thousand times denser than today's chips.

What they work on
- Model, design and synthesize specific synthetic DNA sequences, varying base pairs, sequence, length and crystallinity, for integration with organometallic halide perovskite semiconductors.
- Develop and characterize hybrid perovskite-DNA biomaterials to learn how DNA and the semiconductor interact electrically and optically to produce multiple memory states.
- Build high-density perovskite-DNA non-volatile memory arrays, integrate them with optoelectronic systems and CMOS back-end-of-line circuits, and demonstrate data storage and in-memory computing.
More about the research
Synthetic DNA is the densest known storage medium and can preserve information for very long times, but reading and writing it chemically is costly, error-prone, about a million times slower than silicon memory, and incompatible with standard CMOS (complementary metal-oxide-semiconductor) chips. This project asks whether DNA can instead serve as part of an electronic device built on ordinary chip technology.
Why it matters
Hybrid DNA-semiconductor memory could make data storage far denser than current chips while keeping it compatible with standard CMOS manufacturing. That could help the electronics industry meet growing storage needs and speed up artificial intelligence and machine learning hardware through in-memory computing.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
